Our "Bloom or Bust" Promise

Delft Blue, often admired for its blue-purple colouring, is a bulb variety especially well suited to pots & containers.

Hyacinthus orientalis ‘Delft Blue’ is a spring classic: neat, glossy green foliage topped with a well-filled spike of softly scented, mid-blue bells. It brings a calm, composed note to the front of the border and is especially charming in pots placed by the door, where the fragrance can be properly enjoyed.

  • Colour: mid-blue with a gentle violet cast
  • Fragrance: softly scented
  • Best for: pots and containers, edging paths, and drift planting for a serene wash of colour
  • Hardiness: Fully Hardy

Bulb size: 15/16. Plant in autumn for a polished display in March and April.

Where to Plant:

Hyacinthus 'Delft Blue' (Hyacinth) needs full-sun, partial sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 10cm apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting bulb according to local conditions.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
